This is very true, any bigger than a 351 and you'll have to cut down the shock towers. I have a 351w set up in mine and believe me, The hedmen headers are a ***** to deal with! about 1/4" of clearance between them and the shock tower. Doesn't make changing spark plugs easy either.
As thunderbolt mentioned, I think your best bet for more cubic inches would be to stroke the motor. If you do go with a 351 engine like this though I would suggest getting ceramic coated headers. You'll likely be changing out starters fairly often without them. Also, get a radiator from Mustangs Plus that has the passenger side top inlet and the driver side bottom outlet. This part was crucial!!! These engines can overheat easy,... especially with the dinky size of their radiators. Good luck!
